Very limited

San Jacinto County, TX: USDA's soil survey calls 85% of the county "Very limited" for a septic leach field. Practically, that rules out a simple gravity system for most of the county - 85% of it sits in USDA's most-constrained bucket. The county spans 569.244 square miles, home to 29,326 people.

What this number does and doesn't tell you
